Easy gamerscore booster..

Bioshock is a great game, and the achievements aren't really hard

but if you want EASY, get Naruto: Rise of a Ninja, COD4, or GTA4

I've heard Avatar is, too

so check that out

nba 2k6.

you can get 1000G in 30minutes

Bioshock's achievements are easy to get, but it's a long game. But it's also a great game, so worth the time.tanc006

(since your renting) i recommend if you have any guitar hero games(you currently own) rent AEROSMITH. alot of achievements. you can also use your controller for play too(y)

Bioshock is good for achievements and a GREAT enjoyable game.
